Abstract: 1,255,860. Decanting valve. I. J. R. COOKMAN. 3 July, 1970 [7 July, 1969], No. 34096/ 69. Heading BID. [Also in Division F2] A valve, which is particularly suitable for use in the dewatering of sewage sludge by decantation, comprises a cylindrical shell 3 having a plurality of ports 11 formed therein, the ports being arranged in a helical pattern, and a square shaft 13 which is arranged for rotation within the shell and which has disposed thereon a plurality of spaced valving members 23, each valving member being arranged to co-operate with a given port and being retained between adjacent valving members by means of spacer elements 24. The valving members each comprise upper and lower plates 25 which are welded to a square section sleeve 26 that fits over shaft 13, are welded to a broken peripheral band 27, and are welded to U-shaped bands 30, the arrangement being such that each valving member has two diametrically opposed recesses 28 of which only one is open at the member ends and at the member periphery. The valving members are so arranged upon the shaft that the open recesses are all aligned and, accordingly, rotation, of the shaft places one open recess adjacent a port 11, (Fig.-3, not shown). The shaft 13 is carried by a support 14, 15 which, by way of rollers 16; rides on the top of shell 3, and is operable by a handwheel having a position indicator 22. When disposed in a sludge containing vessel 2, drainage of liquid from a given level in the vessel is achieved by appropriate positioning of the shaft 13 and hence selection of a given port 11 and associated recessed valving member 23. Liquid so supplied to the shell is drained therefrom via pipe 7 and valve 8, the latter valve being operable by a handwheel 9. The shell may have ribs 11 on its outer periphery to prevent vertical flow of liquid near the shell and in the vessel.

Abstract: 1,221,363. Photo-electric sorting apparatus. ELCEMCO Inc. July 17, 1968 [July 17, 1967j, No.34109/68. Heading G1A. An air blower is used to aid the transport of objects to be sorted through a photo-electric sorting device. The blower provides a predictable velocity of the objects, thereby increasing the reliability of the sorting operation as compared with gravity feed sorters. The objects 15 which may be coffee beans, peas &c. are stored in a bin 14. Two feed spouts 19 allow filling of a cylindrical hopper 16 with objects to a level controlled by the setting of adjustable chutes (46), Fig. 4 (not shown), attached to the ends of spouts 19. Inside the hopper 16 are four feeder wheels 17 driven by a motor and pulley system (21-29) Fig. 1 (not shown) having a number of pockets 31 by which objects are flung forward along the path represented by arrows 33. The wheels 17 also have pockets (44) Fig. 5 (not shown) on the side edges to carry objects and cause circulation of objects within the hopper 16. Those not picked up by pockets 31 fall back down and are recirculated. Each wheel 17 is associated with a chute 18 into which the objects are flung one by one. An air blower 38, 40 is provided for each pair of chutes 18 and aids the movement of the objects into glass tubes 20 (of rectangular crosssection to prevent object spin or slowing down). A photo-electric viewing head on each tube 20 determines if objects are too light or too dark by reflection of light from their surfaces and unwanted objects are sorted out by a pneumatically operated spring-loaded plunger 32, which rejects them into receptacle 28, while wanted objects continue to receptacle 26. The feed wheels 17 have pockets suited to the shape of the objects to be sorted. In order to change the wheels, the hopper 16 is retractable (after detachment of chutes 18 and the chutes attached to spouts 19). The air-flow from blowers 38 also separates out chaff and lightweight debris.

Abstract: 1404366 Selective signalling CENTURY INTERNATIONAL CO Ltd 24 July 1972 34548/72 Heading G4H Documents such as cheques, credit cards bear enciphered information to make unauthorized use and counterfeiting more difficult. In one embodiment, a cheque stub 1, Fig. 1, is printed with a randomly generated alphabet display in which each letter is associated with a mark 11 or a space. The 26-bit random-word corresponding to the alphabet display is enciphered with the binary coded cheque number using transformation matrices and a feedback shift register, Fig. 2 (not shown), and the resulting enciphered infromation is printed on portion 3 of the cheque. Each account is assigned a unique code name known to the holder of the account, and when filling in a cheque, the account holder records a code signature 5 comprising marks and spaces appropriate to the letters of the code name according to the alphabet display 1 which is different for each cheque. Fig. 3 shows apparatus for checking the authenticity of a cheque and the authority of the user. The account number 9 is sensed and used at 74 to retrieve the corresponding code name which is entered in a register 64. The binary coded cheque number 7 is sensed and compared at 76 with the numbers of cheques previously drawn on the account and held in a store 72 to provide one input to a gate 78 if a cheque with that number has not been used previously. The enciphered information 3 is sensed and deciphered using the reverse process to the enciphering operation. The information is fed to a transformation matrix 44 the outputs of which are selectively supplied to a shift register 46 and a counter 54. Register 46 is shifted backwards a number of times equal to the number set in counter 54, at the end of which operation matrix 50 supplies the deciphered random alphabet display word to register 60 and the cheque number to register 68. The recovered cheque number is compared at 70 with the sensed cheque number 7 to provide a second input to gate 78 on equality. The contents of registers 60, 64 and 66 are gated together at 62 to provide the final enabling input to gate 78 if the sensed code signature corresponds to the retrieved code name as encoded by the deciphered alphabet display word. In a further embodiment, a credit card is provided with a binary coded account number and an encipherment of the account number with a code name for that account. When the card is used, the holder fills in a charge slip with a code signature as above, the alphabet display being provided on the charge slip instead of on the card. The card is then sensed and deciphered to check the account number, and the charge slip is also sensed to check the code signature, both checks being performed in a manner similar to that described above, Fig. 7 (not shown).
